Some Twitter users said that based on his campaign platform and political values of democratic socialism, it was a hypocritical move.

Among the headlines:"Bernie Sanders' third home puts a new spin on 'socialism' in America."

Combating rumors that Sanders used campaign donations to fund his purchase, his wife told a local news outlet that they sold another property to get the money for the new house.

"My family had a lake home in Maine since 1900, but we hadn’t had the time to go there in recent years, especially since my parents passed away," Sanders’ wife, Jane O’Meara Sanders, said a written statement. "We finally let go of it, and that enabled us to buy a place in the islands -- something I've always hoped for."
